Stacked sheets synchronised buffer store - has pallet runners circulated at two levels over three section track

摘要

In the absence of removal transport a two-tier track admits completed sheet stacks from a profiling rolls stand, reducing the roll down time. Timed chains withdraw a runner loaded stack over three track sections and return the empty runner. The middle track section is fixed and the end track sections provide lifting and lowering. The runner (15) carried stacks are built and unloaded at vertically movable end tracks respectively. Wheel (21) driven chains pick up and transport a runner on an upper level with intermediate storage on a fixed track section (3). Empty runners return on a lower level.
